With all Postfix versions, you would set relayhost to a name that resolves to multiple IP addresses (in DNS or /etc/hosts). In my first 10+ years in IBM I had: relayhost = $mydomain i.e. use the MX records for the local domain. Later I had to change that to relayhost = [na.relay.ibm.com] i.e. use the A records for a regional mail cluster. > Will it possible to configure secondary outbound mail server on Postfix ? > Postfix will have high availability functionality ? Having multiple servers helps. With Postfix 3.0.0 you could use this: sender_dependent_relayhost_maps = randmap:{[host1], [host2]} You could even list host1 and host2 different numbers of times to get a load split different from 50/50.
